Chapter 4: Q. 26 (page 239)

Immigration reform A news organization wants to know what percent of U.S. residents support a “pathway to citizenship” for people who live in the United States illegally. The news organization randomly selects registered voters for the survey. Describe how under coverage might lead to bias in this study. Explain the likely direction of the bias.

Short Answer

Expert verified

The study's sample is skewed since it only includes persons who are lawfully present in the United States and excludes those who are here in the country illegally.

Step by step solution

01

Given information

We have to describe how under coverage might lead to bias in this study and explain the likely direction of the bias.

02

Simplification

A news outlet is curious as to what percentage of Americans support a "road to citizenship" for persons living in the country illegally. For the poll, the news outlet chooses registered voters at random.

The study's sample is skewed since it only includes persons who are lawfully present in the United States and excludes those who are here in the country illegally. Because the sample covered does not clearly describe the survey's result because they are citizens and have no concerns, the sample cannot clearly define the survey's result. As a result, the study is under-researched and under-estimated.

Supplements for testosterone -As men age, their testosterone levels gradually decrease. This may cause a reduction in energy, an increase in fat, and other undesirable changes. Do testosterone supplements reverse some of these effects? A study in the Netherlands assigned 237men aged 60to 80 with low or low-normal testosterone levels to either a testosterone supplement or a placebo.

Explain why it was necessary to include a control group in this experiment.

Layoffs and “survivor guilt” Workers who survive a layoff of other employees at their location may suffer from “survivor guilt.” A study of survivor guilt and its effects used as subjects 120students who were offered an opportunity to earn extra course credit by doing proofreading. Each subject worked in the same cubicle as another student, who was an accomplice of the experimenters. At a break midway through the work, one of three things happened:

Treatment 1: The accomplice was told to leave; it was explained that this was because she performed poorly.

Treatment 2: It was explained that unforeseen circumstances meant there was only enough work for one person. By “chance,” the accomplice was chosen to be laid off.

Treatment 3: Both students continued to work after the break. The subjects’ work performance after the break was compared with their performance before the break. Overall, subjects worked harder when told the other student’s dismissal was random.

Describe how you would randomly assign the subjects to the treatments

a. using slips of paper.

b. using technology.

c. using Table D.

Seed weight (2.2) Biological measurements of the same species often follow a normal distribution quite closely. The mean weights of seeds of a variety of winged beans are approximately normal, with a mean of 525milligrams (mg) and a standard deviation of 110mg.

a. What percent of seeds weigh more than 500mg?

b. If we discard the lightest 10%of these seeds, what is the smallest weight among the remaining seeds?

Frozen batteries Will storing batteries in a freezer make them last longer? To find out, a company that produces batteries takes a random sample of 100 AA batteries from its warehouse. The company statistician randomly assigns 50 batteries to be stored in the freezer and the other 50 to be stored at room temperature for 3 years. At the end of that time period, each battery’s charge is tested. Result: Batteries stored in the freezer had a significantly higher average charge. What conclusion can we draw from this study? Explain your reasoning.

Stronger players A football coach hears that a new exercise program will increase upper-body strength better than lifting weights. He is eager to test this new program in the off-season with the players on his high school team. The coach decides to let his players choose which of the two treatments they will undergo for3weeks—exercise or weight lifting. He will use the number of push-ups a player can do at the end of the experiment as the response variable. Which principle of experimental design does the coach’s plan violate? Explain how this violation could lead to confounding.
